ELEVATOR AND CARRIER.

SFECIIEICATION forming part of Letters Patent No. 344,941, dated July 6, 1886.

Application filed June 19, 1885. Serial No. 169.188. (No model.)

To all whom it may concern Be it known that I, MARoUs W. CHAMBER- LAIN, a citizen of the United'States,and aresident ol' Branchville, in the county of Sussex and State of New Jersey, have invented certain new and useful Improvements in Elevators and Carriers, of which the following is a specification.

My invention relates to an improved elevaio tor and carrier, and belongs to that class wherein a single draft-rope is made to perform the double function of elevating the load and mov-v ing it from one point to another along a suitably-prepared track.

I5, It is designed chiefly for use with devices for loading and unloading` hay, grain, or similar material.

It consists of a carriage traveling upon a suspended tramway and provided with a pulley to permit the hoisting of the load and an automatically-working catch or lock, whereby the load is securely locked to the carriage after it has been raised,and which will be automatically unlocked or opened when the carrier has returned to its loading-point by a xed block or stop upon the tramway.

In the accompanying drawings, Figure l is a side elevation of my improved device, partly broken away. Fig. 2 is a sectional view of a 3o part of my device on line x of Fig. l. Fig. 3 is a central vertical section on line y y of Fig. 2; and Fig. 4 is a horizontal section, 1ooking down on line z e of Fig. l.V

The construction of my device is as follows: A Usb-.ipod frame, A, is joined together at its lower part by bolts (t a,and made to project upward so as to embrace a track, B, and this frame has pivoted to its upper part flanged wheels C O, two on each side, and adapted to 4o bear and roll upon the upper surface of the track. A central annular ring, D, is formed in the lower part of the frame A, in position to be immediately beneath the position occu i pied by the track,and an inward]y-projecting flange, d, is formed at the lower side of this ring. A frame, E, is suspended to this ring D by means of an upwardly-projecting annular ring, e, with an outwardlyprojecting flange, cause the load to rise.

e', which will bear and rotate upon the flange d of the ring D. The frame E is formed of two 5o parallel walls, e2 c", curved outwardly at their lower side to form a conical or bell-shaped socket, c3, to receive the handle or bail of an elevatingpulley, F, and a cross-partition, et, is formed between the two walls e? e2, to form a bearing for one side of the bail or handle of the pulley F when the latteris locked in position. Ahook or lockingblock, G, is pivoted between the walls e2 e2, so asto swing under and against the handle of the pulley F on the side oppo-A 6o site the partition et, and this hook is provided with a projecting arm, g, in position to be pressed upon by the bail of the, pulley when the latter is forced into the socket e3, and to force the hook Gr into locking position. A t5 locking-block, H, is also pivoted between the walls e2 e2, and this block is provided with laterallyproj ectin g lugs h h,adapted to engage upwardly-projecting arms g2 g2 upon the lockinghook Gr, the body of the lock H being 7o made to lie between said arms when the hook is locked. Two upwardly-projecting lugs, h li', are formed upon the upper side of the block H, in position to be operated upon by a fixed stop-block, I, upon the under side of the tramway, and an annular ring, 7i, is secured to and made to include the lugs la lt. At one end of the frame E a pulley-wlieel, K, is pivoted between the wallset e2, and at the opposite end a ring or eye, L, is formed. The hoistingpulley F is made with an upwardly-projecting bail or handle having a round body, f, provided with an enlarged spherical head, j", to permit a firm hold thereon by the locking devices.

In use the hoisting and draft rope M is secured by one end to the ring L, preferably by passing it through the same and tying it in a k not. The rope is then led down around the pulley,F,and then up over the hoisting-pulley 9o K,and ol' to a convenient position forapplying the power. Suppose, now, the lock in the frame E to be opened-that is, as shown in Fig. l-and the load placed upon the pulley F.` Then a pull upon the draft-ropevM will The stop-block I upon the under side of the tramwaywill, by engaging the lock-block H, prevent the carriage from moving tillthe bail or handle of the pulley F has entered the socket e3, raised the hook G to its locking position, and allowed the lugs h on the block H to drop behind the arms g2, Fig. 3, on the hook G, thereby securing the load to the carriage. A further pull upon the draft-rope will cause the carriage to travel along upon the tramway.

` The end sought in connecting the frame E tothe carriage by means of theannular flanged rings d and e is to permit the working of the carrier from either end of the tramway With. out reversing the position of the carriage upon the track.

Io make the necessary change in the direction of the draft along the tramway, it is only necessary to bring the carriage over the stopblock, so that the hoist-pulley will be unlocked or loosened therefrom, as shown in Fig. l, and to give the frame E a half-turn in its annular bearing by means of the draft-rope, and the carrier is ready for use on the opposite direction.

In making the locking-hook Git is not necessary to have two upwardly-projecting lugs, g2, as one will serve the purpose, by cutting away the locking-block H to accommodate it to the change.

It Will be readily seen that While the carriage itself will work equally Well from either end of the track'to the stop-block, it will be impossible to force the locking-block H past the said stopblock Without bringing it into l position to unlock the hoisting-pulley and causing the annular ring` h3 to Surround the stop-block, and then' rotating the swiveled frame in its bearings and again locking the bail of the pulley, so as to allow the ring h3 to drop away from around the stop-block, as shown in Fig. 3.

1. In an elevator and carrier, the combination, with a traveling carriage and with a frame swiveled thereto having a bell-shaped socket to receive the bail of a pulley, and provided with a locking-hook, of a pivoted locking-block having upwardly-projecting arms to engage a fixed stop-block upon the track and withdraw said lock-block from its locking position to free the bail of the pulley, and when so withdrawn to embrace the stop-block and prevent a movement of the carriage upon the track, substantially as and for the purpose set forth.

2. In an elevator and carrier, the combination, with a swiveled hoisting-frame and with a pivoted locking h'ook therein, of a pivoted locking-block provided with upwardly-prouiecting arms terminating in an annular ring, substantially as and for the purpose set forth.
